These are the Tarr Steps, a 'clapper' bridge on the river Barle in Devon. They are about 1000 years old and each crossing stone weighs about five tons. The bridge was allegedly built by the Devil to win a bet. I don't think he was about when we pitched up but we saw a horse, plenty of children and dogs , and a couple of land rovers that crossed the river. Inevitably there were chav types who parked up as close as possible to avoid the car park charge and a walk, thus blocking it for other drivers.
Anyhow we had a right old time of it crossing back and forth and splashing about.
